This is the information about the Ten Two performance modifications for the Beech Model 18 aircraft.

Dear Twin Beech Owner:

Ask Me All Your Questions

It is with a great deal of pleasure and pride that Conrad International Corporation, Inc. announces the CONRAD 10,200, a modern executive type aircraft, incorporating the latest developments of Safety and Performance.

This is the result of ten years of intensive research and development, costing a tremendous amount of money. This work was done as the result of a poll of executive aircraft pilots at the end of Airline Training Incorporated’s first seminar in 1951. They replied in favor of increasing the gross weight and performance of the Twin Beech.

Working with the best aerodynamicists in the country, we made many refinements to the Beech, and, after a full series of dynamic, static and performance tests in July of 1961, we were certificated by the F.A.A. at 10,200 lbs. gross weight for take-off and 9,800 lbs. for landing without Jato or dump chutes.

The safety and performance of the Conrad 10,200 exceeds that of any aircraft in its class and at a cost amazingly below that of others.

Very truly yours,
W. H. Conrad
